A handle for an oral-care implement, the handle comprises an electrical motor arranged to drive an output element structured and configured to couple the handle and a head attachable to and detachable from the handle; and a microcontroller for controlling the motor and to cause the output element to vibrate in (a) at least one oral-hygiene mode during which the oral-care implement is being used for an oral-hygiene routine, wherein the output element is vibrating at a substantially constant frequency, and (b) a disinfection mode during which the handle is being disinfected, before or after being used for the oral-hygiene routine, wherein the output element is continuously vibrating at a modulated frequency alternating within a frequency range of between about 140 Hz and about 250 Hz, for a duration of the disinfection mode.

Handle for oral-care implement for safe and hygienic use by multiple users and method of disinfecting the same

A handle for an oral-care implement for safe and hygienic use by multiple users includes an electrical motor and a detachable head. The handle has a display for displaying instructions to control functional operation of the handle, a microcontroller for controlling the motor and the display, and at least one switch to allow a user to control the functional operation of the handle, including causing the output element to vibrate in at least one oral-hygiene mode having an oral-hygiene frequency and causing the output element to vibrate in a disinfection mode when the handle is being disinfected before or after being used for the oral-hygiene routine. The disinfection mode has a modulated frequency, different from the oral-hygiene frequency, and alternating up and down between a low modulated frequency and a high modulated frequency, wherein the high modulated frequency is at least 50 percent greater than the low modulated frequency.

Handle for oral-care implement having display and procedure for cleaning and disinfecting the same

A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.

Head for an oral care implement

A toothbrush head, including at least one two-component cleaning element and at least one bristle tuft element, is produced by injection molding. To achieve high design flexibility regarding the arrangement of the two-component cleaning elements and regarding the material choice, the two-component cleaning elements are manufactured separately or in an upstream molding step. Then the two-component cleaning elements, together with the bristle tufts, are over-molded with plastic material, to form the brush head or a part thereof.

Toothbrush heads comprising a two-component cleaning element and method for producing the same

Toothbrush head

A brush implement for the use with a skin treatment device, the brush implement having bristles of a first type and bristles of a second type, wherein the bristles of the first type are longer than the bristles of the second type and are positioned closer to the outer contour of the brush implement and the bristles form at least three distinguishable sectors.

Implement for a skin treatment device

An oral-hygiene implement having a housing, a first carrier on which at least one first oral-treatment element is mounted, a second carrier on which at least one second oral-treatment element is mounted, wherein at least the first carrier element is mounted for driven oscillatory movement with a peak amplitude value relative to the housing and wherein the first and second oral-treatment elements are arranged such that the first oral-treatment element contacts the second oral-treatment element at least once during each oscillation period of the first carrier at a contact amplitude value smaller than the peak amplitude value and moves the second oral-treatment element out of its initial position until the peak amplitude value is reached.

Oral-hygiene implement and oral-hygiene device comprising an oral-hygiene implement

A brush head section for an oral care device is provided. The brush section includes an insert being made from a first thermoplastic material by injection-molding, at least one oral cleaning element and a cleaning element carrier consisting of a second thermoplastic material or a second thermoplastic mixture. The insert and the at least one cleaning element are partially embedded into the cleaning element carrier by over-molding and the cleaning element carrier at least partly engages behind the insert. The hardness of the second thermoplastic material is less than the hardness of the first thermoplastic material.

Method and device for producing a brush head section for an oral care device and brush head section produced by said method and/or said device

A cleaning section of an oral hygiene device is disclosed. The cleaning section includes a cleaning element carrier mounted for oscillatory rotation around a carrier rotation axis; a gear unit arranged for being coupled to a drive shaft of a handle of the oral hygiene device, which drive shaft defines a drive shaft rotation axis in an attached state, and the gear unit further having an actuation element for transferring motion from the drive shaft to the cleaning element carrier during operation. The carrier rotation axis is parallel to the drive shaft rotation axis and is disposed at a distance to the drive shaft rotation axis.

Cleaning section of an electric oral hygiene device

An oral cleaning section is disclosed. The oral cleaning section includes a first carrier having a cleaning side on which at least a first cleaning element is mounted and a second side opposite to the cleaning side, a second carrier having a cleaning side on which at least a second cleaning element is mounted, at least one aperture being formed in the first carrier such that the aperture extends from the cleaning side to the second side, with the second cleaning element extending through the aperture. The second carrier is arranged underneath the first carrier such that the cleaning side of the second carrier is underneath the second side of the first carrier and laterally extends beyond the aperture in at least a first direction. The first carrier and the second carrier are arranged for relative movement to each other.
